摘要
目的:查明车河镇车河村小学、灰乐屯、拉宜屯水砷超标原因,为政府改水工程的整改提供科学依据。方法:对三地相关水质砷污染超标展开卫生学调查,并采集相应的水质进行实验室检测。结果:三处农村饮水工程的水砷含量范围在0.120 mg/L～0.175 mg/L,平均值为0.149 mg/L,超过国家标准0.05 mg/L的3倍,其中车河村小学、灰乐屯、拉宜屯的水中砷含量其平均值分别为0.128 mg/L、0.148 mg/L、0.171 mg/L,分别超过标准限值的2.6倍、3.0倍、3.4倍。结论:矿产品开发产生的废水和废碴的不科学处理是导致水源中砷污染的主要原因,应引起政府相关部门的重视,切实做好高水砷污染地区的饮水工程项目。
Objective： To find out the reasons of excessive arsenic in the drinking water in Chehe Pr-imary School,Huile and Layi villeges,and provide a scientific basis for the rectification of water engineering for the government.Methods： Hygiene investigation was made.The average is 0.149mg/L,which is three times beyond the national standards 0.05mg/L.The average of arsenic in water in Chehe Primary School,Huile and Layi villages were 0.128mg/L,0.148mg/L,0.171mg/L which were 2.6 times,3.0 times and 3.4 times beyond the national standards.Conclusion： The main reason of arsenic pollution in water source was the waste water and waste residue from mineral products.So the government should to make better drinking water project heavy arsenicpolluted areas.
